You don't say where you are, but [broken link removed] in Ballymount do Karndean and I remember a couple of years ago they had a fairly decent range on display, don't know about now but you could try phoning them.
I fell for the hype on the karndean website and had it installed in my bathroom by a specialist fitter. The product just looks like vinyl tiles, and the fitting was atrocious. I purchased through my local supplier - Parlane Flooring Ltd, London N9 9JS. When i logged my complaint with them they were defensive and firstly blamed my bathroom fitter for leaving glue on the floor and then said the gaps in the tiles looked ok. This was unacceptable as it was fitted in the bathroom and water and dirt will sit there. I then complained to karndean manufacturer who said the fitting had nothing to do with them and even though i will be given a warranty the warranty will not be upheld if i dont use karndean's cleaning solutions. It has been a costly mistake.
My partner used to work for Karndean at their head office/work premises in the cotswolds.Info from her is it is quite expensive,but the main thing is it has to be layed by someone who knows what they are doing.Karndean have their own fitters who used to go out onsite and lay the flooring themselves so if anything went wrong Karndean had to sort it out.
